I was engrossed and believed everything he said right up to where he said those little hand warmers are great. They're pish. They require boiling water before every use and don't last all that long. Unfortunately, that makes me dubious about the rest of his claims.
Energy wise, they last up to 60% as long as a block of ice in a plastic bag wrapped in a thin layer of foam so it doesn't frostbite you. The benefit is the ability to recharge them in the fridge or even in a cool place instead of the freezer.
also those hand warmers seem like they're bad because they're tiny not because their chemistry is flawed.
